Given that the standard oxidation potentials `(E^0)` of `A|A^(+3)` and `A^(+1)|a^(+3)` are 0.20V and -0.40V respectively, the `E^0` of `A^+//A` is

A

`-1.40V`

B

`-0.20`

C

`-0.60`

D

`+0.20`

Text Solution

Verified by Experts

The correct Answer is:
A

`DeltaG_(3)=DeltaG_(1)+DeltaG_(2)`
`-1xxFE^(@)=0.80F+0.60F`
`E^(@)=-1.40V`
